Alternate Functions of Port L

The Port L alternate pin configuration is as follows:

• OC5C – Port L, Bit 5

OC5C, Output Compare Match C output: The PL5 pin can serve as an external output for the Timer/Counter5 Out-

put Compare C. The pin has to be configured as an output (DDL5 set) to serve this function. The OC5C pin is also

the output pin for the PWM mode timer function.

• OC5B – Port L, Bit 4

OC5B, Output Compare Match B output: The PL4 pin can serve as an external output for the Timer/Counter 5 Out-

put Compare B. The pin has to be configured as an output (DDL4 set) to serve this function. The OC5B pin is also

the output pin for the PWM mode timer function.

• OC5A – Port L, Bit 3

OC5A, Output Compare Match A output: The PL3 pin can serve as an external output for the Timer/Counter 5 Out-

put Compare A. The pin has to be configured as an output (DDL3 set) to serve this function. The OC5A pin is also

the output pin for the PWM mode timer function.

• T5 – Port L, Bit 2

T5, Timer/Counter5 counter source.

• ICP5 – Port L, Bit 1

ICP5, Input Capture Pin 5: The PL1 pin can serve as an Input Capture pin for Timer/Counter5.

• ICP4 – Port L, Bit 0

ICP4, Input Capture Pin 4: The PL0 pin can serve as an Input Capture pin for Timer/Counter4.
